Medical Xpress / CAR T-cell therapy accelerates intestinal healing in aging mice
Ever notice that as you get older, some foods no longer sit with you the same? This could be due to a breakdown of the intestinal epithelium, a single layer of cells that forms the organ's lining. The intestine plays a crucial ...
Medical Xpress / Tricking tumors into marking themselves for destruction with focused ultrasound
USC biomedical engineers have found a way to make a solid tumor paint a target on its own back in order to train the body's immune system to find and destroy it.
Medical Xpress / Scientists uncover key driver of treatment-resistant cancer: Genome-scrambling enzyme points to new treatments
University of California San Diego researchers have discovered the enzyme responsible for chromothripsis, a process in which a single chromosome is shattered into pieces and rearranged in a scrambled order, allowing cancer ...
Phys.org / Wintertime spike in oceanic iron levels detected near Hawaii
Around the world, phytoplankton in the upper ocean help to cycle key nutrients and regulate Earth's climate by absorbing carbon dioxide. These photosynthesizing organisms rely on dissolved iron as an essential micronutrient, ...
Medical Xpress / Antibody formulation could enable simple injections instead of lengthy hospital infusions
Antibody treatments for cancer and other diseases are typically delivered intravenously, because of the large volumes that are needed per dose. This means the patient has to go to a hospital for every treatment, where they ...
Phys.org / Shape-shifting cell channel reveals new target for precision drugs
From small ions to large molecules, cellular gates control what can pass in and out of cells. But how one such gate, called pannexin-1 (PANX1), can handle vastly different cargo sizes has remained a long-standing mystery.
Phys.org / Exposing a single active site in nanoclusters boosts catalytic activity for green energy
There is a dire need for selective catalysts that allow us to consistently achieve a desired outcome in a chemical reaction. It is this consistency that allows for more efficient, energy-saving ways of producing fuel. A team ...
Medical Xpress / Blocking collagen signaling boosts drug delivery in pancreatic cancer
Pancreatic cancer is one of the deadliest malignancies, with survival rates remaining dismally low despite major advances in oncology. One of the key reasons lies in the disease's unique fibrotic microenvironment—a dense, ...
Medical Xpress / Missing myelin in key brain cells erases first wave of sensory signals
Our nerve cells are surrounded by a protective layer (myelin). This protective layer allows signals to pass between cells incredibly quickly. But what happens when this layer goes missing from cells that transfer signals ...
Phys.org / Black hole ejects matter at 20% light speed in sun-like magnetic event
An international team of astronomers, led by SRON, has observed a sudden outburst of matter near the supermassive black hole NGC 3783 at speeds reaching up to 20% of the speed of light. During a 10-day observation, mainly ...
Phys.org / A pioneering study on the feasibility of asteroid mining
Much remains to be known about the chemical composition of small asteroids. Their potential to harbor valuable metals, materials from the early solar system, and the possibility of obtaining a geochemical record of their ...
Phys.org / Earliest botanical art hints at prehistoric mathematical thinking
A new study published in the Journal of World Prehistory reveals that some of humanity's earliest artistic representations of botanical figures were far more than decorative; they were mathematical.
